Mendel's work with pea plants in the mid 1800s, earned him the title "The Father of Modern Genetics". His work is discussed in most textbooks as an introduction to genetics as his hypotheses on heredity are still accepted. He observed 7 traits in pea plants including flower color, seed color, seed shape, pod color, pod shape, flower position, and plant height. This activity provides an accessible tactile model of seed shape using beads for activities in which Mendel's work is modeled.
This activity is adapted from the AGS Biology book by Charles J. LaRue, Ph.D. published in 2004

Modeling Mendel’s Experiments
(Procedure is also attached below as a Word file.)
What did Mendel prove in his experiments with pea plants? In this investigation, you will model the genetic crosses that resulted in Mendel’s F2 generation.
